Our systems do more than soften your water

Soap scum, etched glassware and dry, scratchy skin caused by hard water are bad enough. Commers softeners can also solve problems with hydrogen sulfide, with its “rotten egg” smell,” and iron, which causes a metallic taste and smell, rust stains, and eventually severe damage to plumbing and appliances.
